So far the REBELS sources are only continuum-detected in one ALMA band, therefore we cannot directly measure the dust temperature from fitting the dust SEDs. But [1]} estimate the temperatures of REBELS sources using a novel analytical method that uses only the [CII] line and its underlying dust continuum [2]}. They find an average \(T_\mathrm {dust}\simeq 46\,\mathrm {K}\)  for the REBELS sources (Fig. REF ) – broadly consistent with the more direct multi-band measurements of [3]}, [4]} for galaxies at similar redshifts.
